Animal vision
Animal vision varies widely among species, adapted to their environments and survival needs. Some animals, like eagles, have exceptional sharpness and focus, allowing them to spot prey from great distances. Others, like dogs, see fewer colors but have better motion detection and night vision. Many animals perceive ultraviolet or infrared light invisible to humans, enhancing their ability to hunt or navigate. The structure of their eyes—such as the number of photoreceptors, the shape of the retina, and eye placement—shapes how they see the world. Overall, animal vision reflects specialized adaptations that help them find food, avoid predators, and communicate effectively.
